Using a common area sensor to build a high resolution electronic camera requires a large sensor chip with an incumbent high cost. Using a line sensor results in slow imaging and therefore limited applications. An electronic camera using a small sensor chip with high speed imaging is therefore provided. A two-dimensional imaging device that is narrower than an area sensor subscans the imaging plane of the lens system by means of a scanning device. The charge transfer register of the two-dimensional imaging device is driven by an X clock generator in the opposite direction and at the same speed as the subscanning speed, thereby achieving TDI operation and high speed image capturing.
